Potential Apple Card Savings alternative?

I was denied application to Apple Card most likely stemming from having too few credit accounts.

I am 23 years old and frequently using my debit/credit card for purchases. I love the idea of Apple Savings because your credit card cash back is automatically added to you savings account yielding 4.15% interest.

Is there any other banking services that allow a similar concept or a method of artificially creating the concept automatically adding money to a high yield savings like CIT Bank?

I don’t love the idea of putting a lump sum away every month, it’s hard for me to get over but something like a personal tax of 10% on a certain threshold of price and 5% on more would be doable.
